I've seen similar comments on this, but not necessarily the same issue I'm seeing...
As with many issue's with the ICS install, this is one of those where it "suddenly" began with no explanation as to why when previously everything was working fine. I have two Skyrockets and one started to experience this while the other did not... then suddenly, just as though an internal timer had been set, it also began to experience the same issue. I will add that the second phone is my test phone and has nothing installed other than what came with the original ROM.
SUMMARY:
Initially my battery life was awesome, but then suddenly saw a huge drop off; I confirmed it to be a problem with the phone not entering a deep sleep state; obviously I began looking to see what app may be causing this, disabling services, putting phone in airplane mode, etc.... nothing resolved it and as far as I could determine there was nothing unusual about any app running... a reboot ALWAYS resolved the problem.
ANALYSIS:
I determined that making a connection to any charging source "triggered" the issue... Using CPU Spy I could confirm that the phone would enter Deep Sleep mode; I did this multiple times (resetting timers) without fail. I then plugged in the phone to the charging source (I've tested both the power block and USB connection), waited until the phone detected the source then unplugged the cable. I then repeated the same steps to confirm Deep Sleep using CPU Spy and this time, the phone would never enter Deep Sleep, but instead would only drop down to 384MHz.... once again a reboot will resolve the issue until the next time a power source is plugged in.
One note to mention, on one of my phones, I have to charge it to 100% before it exhibits the issue while the other will always see the issue regardless of battery level.
I have also confirmed this to occur with a default install of ICS; no apps installed, etc. Is anyone else experiencing a similar situation and if so, any ideas as to what may causing the problem?
